DOOR

Application filed June 11,

This invention relates to door jambs and more particularly to devices of this character which have embodied therewith adjustable means shiftable toward, or from the door to con'ipensate for varying widths of the latter.

It frequently occurs that doors, when constructed of very dry wood, will swell, due to absorption of moisture after same has been put up, to such a degree that it is impossible to close same. This necessitates removing the door from the frame and planing off the free edge thereof suificiently to permit it to pass within the jamb after the door is replaced in the frame. When a door, which is constructed of unseasoned wood, has been in use a short time, said door very often dries out and shrinks, thus leaving a very large opening between itself and the jamb.

This invention has, for one of its objects, the provision, in a manner as hereinafter set forth, of a door jamb which may be expeditiously adjusted relative to the door for the purpose of remedying the defects set forth in the foregoing paragraph and wherein the means for effecting the adjustment will in no way mar or detract from the appearance of the building in which it is installed.

Another object of the invention is the provision of a device of the aforementioned character which will be simple in construction, strong, durable, etiicient in. its use, and which may be manufactured at low cost.

Other objects of the invention will be apparent from a study of the following specification, taken in connection with the accompanying drawings, wherein like char r of reference denote corresponding parts throughout the several views In the drawings Figure 1 is a front elevation of a door jamb constructed in accordance with this invention and showing a part of the support ing frame therefor, a portion of said jamb and frame being shown broken away in section.

Figure 2 is a vertical cross section taken on the line 22 of Figure 1.

Figure 3 is an enlarged horizontal cross section, taken on line of Figure 1 showing a pair of face casings mounted on the frame.

Figure at is an enlarged detail perspective view of the securing plate which is mounted on the frame, and

lower edges of the plates.

1928. Serial No. 284,620.

Figure is an enlarged detail perspective comprising apair of vertical side members 2, 3 and an upper cross jamb member 4t. The members 3 and 4- are provided, on their inner faces, with conventional stop strips 5 and 6 of less width than said members and positioned centrally thereon.

Reference character 7 denotes an upright portion of a door frame which is immovably secured in a wall (not shown) and to which the member 2 is adjustably secured. To the opposite edges of upright 7, a pair of face casings 7 are secured in a manner to extend inwardly of the frame. At its upper end the upright 7 is connected to one end of the cross member 4, and in conjunction with the vertical member 3, forms a support there for.

The member 2 is slidably positioned between the face casings 7 in spaced, opposed relation to the upright 7 to which frame said member is adjustably secured in the following manner. The upright 7 and 1118111" her 2 areprovided with a plurality of superposed, spaced, horizontally aligned openings 8 and 9. To the inner face of the upright 7 are secured a plurality of superposed, spaced plates 10 having threaded recesses 11. therethrough. The plates 10 are so positioned that the openings 11 therein will. register with the openings 8 in the upright. Secured to the opposing face of the member 2, are a plurality of plates 13, arranged in superposed, spaced relation and havinginverted U-shaped passages 1.4 opening at the The plates 13 are so positioned upon, the member 2 that the recesseslt communicate with the openings 9 in said member. Near theiropposite ends, the plates 10 and 13 are provided with openings 12 for the passage of securing screws 12 for anchoring the plates 10 and 13 to the upright 7 and jamb member 2 1espectively. As shown in the drawings, the plates 10 and 13 are countersunk in the upright 7 and jamb member 2 so that their outer surfaces will be flush with the opposed faces thereof.

Threaded bolts 15 couple the member 2 and upright 7 together and have slotted heads 16 positioned in the openings 9. The bolts further include reduced neck portions 17 which pass through the passages 14. in plates 13 and are free to rotate therein. The reduced neck 17 of each bolt provides a pair of spaced shoulders 17 which are adapted to oppose the faces of the plates 13. It is to be understood that the neck portions 17 of the bolts are inserted in the passage 14 prior to mounting the plates 13 on the memher 2. The bolts 15 are then threaded through the openings 11 in the plates 10 and project into openings 8 in upright 7.

On its inner face the member 2 is provided with a removable stop strip 18 which is positioned centrally thereon and is of the same width as the strips 5 and 6. The

. stri l8 besides functionin as a door sto serves to conceal the openings 9 in the jamb member 2 and is secured to said member by screws 19. The upper end of the strip 18 abuts the lower face of the strip 5, while the jamb member 2 is formed at its upper end with upwardly extending spaced legs or guides 20 which embrace the strip 5 and abut the lower side of the cross member 4:. The lower end of the strip 18 is flush with the lower end of the jamb member 2.

In use, the device functions in the follow ing manner The amb member 2, having the plates 13 and bolts 15 thereon, is positioned between the face casings 7.. The bolts 15 are then threaded through the openings 11 in plates 10, thus drawing the member 2 toward the frame 1 by reason of the shoulders formed by the reduced neck 17 engaging the plates 13, as will be apparent from a study of the drawings; VVhenthe member 2 has been adjusted to the desired position, the stop strip 18 is removably secured thereto and the door may then be hung. Should the door shrink or swell after being hung, the

"trouble may beremedied by simply removing the-strip 18, inserting the blade of a screw driver in the slot in heads 16 and screwing a door jamb constructed in accordance with this invention will be readily understood, and, although the preferred embodiment of the invention is as illustrated and described,

it is to be understood that changes in the details of construction may be made which will fall within the scope of the appended claims.

What I claim is 1. In combination, an upright, a door jamb for connection therewith and comprising a vertical, stationary jamb member having a stop strip thereon, a cross jamb member having a stop strip thereon, disposed at right angles to the vertical member and having one end connected thereto and its opposite end supported on said upright, a shiftable jamb member mounted on the upright having guides on its upper end for engaging the sides of the stop strip on the cross jamb member for the purpose of guiding said shiftable member, and means for supporting the shiftable member from, and adjusting it with respect to, the upright.

2. A door jamb comprising vertical, spaced, stationary and shittable jamb members, said shiftable member having spaced openings, a horizontally disposed stationary jamb member extending between the vertical members adjacent the upper ends thereof, stop strips on the inner sides of said jamb members, guides on the upper end of the shiftablemember for engaging the strip on the horizontal member, plates mounted on the shiftable member and having U-shaped recesses communicating with the openings in said member, threaded bolts, having reduced neck portions terminating in an enlarged head mounted in the openings in the shiftable member and rotatably retained therein by the plates, said bolts constituting means for adjustably mounting the shiftable member on a door frame.

3. A door jamb comprising opposed, vertically disposed spaced stationary and shiftable jamb members, a cross jamb member positioned therebetween at the upper ends of said vertical members, sto strips secured on the inner faces of the jamb members, guides, con'iprising spaced, Vertical legs carried by the shiftable member and adapted to slidably embrace the stop strip on the cross member therebetwlen, and means for supporting said shiftable member and for adjusting same toward or from the stationary member.

In testimony whereof, I afiix my signature hereto.
